Specification of Letter: Patent.

Patented May 23, 1916.

Application filed June 10. 1815. Serial No. 88,291.

To all whom 'i' 11 may comm/Ii:

Be it known thatI, ALnna'r F. PFIFFNER, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in Signs, of which thefollowing is a specification.

My invention relates to signs, with spec al reference to si as havingremovable and interchangeable ctters to be used either out of doors orinside and so fastened that they cannot be readily removed by the windor picked oil by passers by, and my ob ect s to provide a baclogroundplate of practically uniform color and to attach to said plate, letters,artistically constructed and so set upon the back-ground plate that theeve of the observer will be attracted especial y to the artistic lettersand their arrangement. 2

It consists essentially in providin I a background plate, which ispreferab v made smooth and ainted or lithographed in any one color andsaid plate hove ed at its edges.

It further consists in letters painted in highly artistic colors anddesigns and in attaching the letters to the back-ground and also insecurin and locking the letters to the back-groom that they can easilybe put in or taken oil and still cannot be h own oil by the wind orpicked oil by mischievous b 5.

he details of construction and mode of operations will be fully set outin the following specification when read in connection with the drawingsaccompanying the same and forming a part hereof in which-- Figure 1. isa perspective view of the sign complete. Fig. 2. is a perspective viewwith the locking frame unlocked and partly raised and showing a plate towhich the letters are attached and one of the means for attaching theplates carrying the letters to the back-ground. Fig. 3. is a sectionalview of Fig. 1. Fig. 4. shows a plan view of one side of a plate towhich the letters are r0 movably attached. Fig. 5. is the same view asFig. 4 with one letter attached. Fig. 0. is a plan view of the oppositeside of Fig. ti showing the mode of attaching the letters. Fig. 7. is apers ective front-view of an embossed letter. Fig. 8 is a back view ofFi t.

l iike characters of reference denote corres ondmg parts in each of thedrawings.

eferring to the drawings 2 designates color.

the back-ground ilate having the beveled edges 4 and 5. 'lhisback-ground plate is preferably painted in a dark gray or brown Alongeach side are set hooks or lugs 6 to which the plates 8, hereinafter tobe described, are reniovably attached. The attaching plates 8 shown inFigs. 3, t and consist of flat pieces. preferably strips of thin metaland of the same color as the back-ground plate, so that when the lettersare attached the plates will appear a part of the liiitk-"ltiillitl andsubstantially invisible which stri is are cut rounding at the ends 12and provided at each end with an openiug 10.

lhe letter 15 is embossed or iuiiitcd upon a plate 16 of ilain surfaceand the surlace is colored preferably the color of the background audthe side edges of the plate 16 are bent down to contact with theattaching date 8. The ends 18 are bent over as shown in Figs. (3 and 8and bent so as to clasp the attaching plate 8 and be easily slidthereon. 'lbeso letters may be each at dill'crent design and color sothat. when assembled they will attract the attention of the passer by.Also since they are formed with a substantial clasp that ou ages theattaching plate. they will not be down oil by the wind or picked oil bymischievous children.

For the purpose of securely locking the plates carryin the letter, thereis provided a frame .20 that consists preferably of a channel bar 22with suilicicnt depth to just rest upon the top of the hooks or lugs (iand cover both the lugs and the ends of the attaching plate. This frameis hinged at one end to the back-ground and provided with a catch orlock .25 whereby it is locked to the back-ground plate when closed down.The frame may be bronzed if the background is of a brown color or it maybe ornamented in any convenient manner according to the taste of theuser.

The manner of assembling and operation of the various parts issubstantially as follows: The letters are slid upon the plates by meansof the clasps and may be arranged so as no two contiguous letters shallbe of the same color or design. Then the plates 8 are brought intoengagement with the books or lugs 6 and may be set horizontally or at anangle, as desired to produce a given etlect. If the letters are large soas to contact with each other then the date 8 would be invisible. Theframe 20 is brought down on the lugs 6 and over the attaching plates 8and locked to the base plate by the catch 25.

It will be observed that a sign constructed in this manner with theletters removable and interchangeable and ornamented, will present a verattractive appearance and can be change daily with the minimum oftrouble and further the letters will remain as securely upon the sign asthough they were each permanently fastened to the background.

Having now I claim is:-

A si n including a backround, lugs secured t iereto adjacent the edgesthereof, at-

described my invention what copies a! thin patent may be obtained (orormation to overlie and conceal the lugs,

and means for securing the frame in fixed relation to the back ground.

In testimony whereof I afiix my signature in presence of two witnesses.

ALBERT F. PFIFFNER.
